Cyberattacks on Operational Technology (OT) Systems Can Have Devastating Consequences – Assessing Preparedness is Key
As cyber threats continue to escalate, industrial organizations must prioritize operational technology (OT) cybersecurity. Recent research highlights the alarming scale of OT breaches, with nearly 3,300 industrial organizations affected by ransomware in 2025 alone. The stakes are high: a single incident can disrupt production, equipment, and essential services, resulting in financial losses, safety concerns, unplanned downtime, and even catastrophic consequences.
To address this pressing issue, Cloud Range has introduced the Cloud Range OT Cyber Readiness Assessment – a free, 28-question tool designed to help organizations evaluate their preparedness for OT cybersecurity incidents. This assessment is more than just a checklist; it provides a practical starting point for IT, security, OT, and engineering teams to evaluate their collective understanding of their environments, coordination of responsibilities, and preparation to detect, investigate, respond to, and recover from cyber incidents affecting industrial operations.
The Cloud Range OT Cyber Readiness Assessment examines seven critical areas that influence an organization’s ability to prepare for and respond to OT cybersecurity threats. These include assessing the environment – understanding critical OT assets, systems, dependencies, and connections between IT and OT environments; recognizing relevant cyber threats and their potential impact on operations, equipment, and safety; bridging the gap between IT and OT teams through shared responsibilities, communication, and decision-making; detecting and investigating suspicious activity; responding to incidents without exacerbating them; and validating readiness through regular exercises and training.
Recent research underscores the importance of preparedness in OT cybersecurity. The Dragos 2026 OT Cybersecurity Year in Review reports that approximately 3,300 industrial organizations were affected by ransomware in 2025, while Palo Alto Networks’ 2026 State of Critical Infrastructure Cybersecurity Report found that 59% of surveyed critical infrastructure organizations experienced a significant security breach in the past year. These findings highlight a central challenge for organizations operating OT and industrial control systems (ICS): preventing attacks is crucial, but so is understanding whether teams can recognize, investigate, and respond quickly and effectively when incidents occur.
An attack does not have to originate within an OT network to affect industrial operations. Compromises involving enterprise IT systems, third-party access, supply chains, or interconnected infrastructure can create consequences for production environments and critical services. This highlights the need for organizations to assess their preparedness in a comprehensive manner, rather than focusing solely on preventive measures.
The takeaway from this is clear: OT cybersecurity requires a proactive approach that includes identifying potential gaps in incident response preparedness. By conducting regular assessments like the Cloud Range OT Cyber Readiness Assessment, organizations can identify areas of improvement and take steps to mitigate risks before they become catastrophic. This is not just about preventing attacks; it’s about being prepared for when incidents inevitably occur, and responding quickly and effectively to minimize disruptions and consequences.
